Remote server system for combining audio files and for managing combined audio files for downloading by local systems

ABSTRACT

A web-based method of combining time coded audio files, having the following steps: (a) a local operator using a web-based interface displayed on a local computer system to access a library of audio files stored on a remote system; (b) the local operator using the web-based interface to select a plurality of the audio files from the library; (c) the local operator using the web-based interface to request the remote system to combine the selected audio files into a single combined audio segment comprising the selected audio files commencing play at audio cue markers; (d) the remote system generating the single combined audio segment by combining the plurality of selected audio files; and (e) the local operator using the web-based interface to download or stream the single combined audio segment.

TECHNICAL FIELD

The present invention relates to systems that combine separate audiofiles, and to systems that manage combined audio files.

BACKGROUND OF THE INVENTION

Nationwide, there are thousands of local radio stations. Many of theselocal radio stations have quite similar playlists and play similarthemed music. These local radio stations all purchase their music fromnational services. The national services supply the music, but thecreation of the “local station identifiers” has always been left up tothe local radio stations themselves.

These unique local station identifiers are typically played both duringand between songs, and can be linked to particular programs, contestsand awards. The variety of local station identifiers can include thelocal stations announcing their call signals, or playing a sound, tuneor jingle. Typically, these unique station identifiers combine musicclips with a voice-over announcement. For example, an announcement like:“This is station KABC playing the hits” can be played over a combinationof clips of various songs that best exemplify the playlist of thatstation.

Designing unique local station identifiers for local radio stations isquite important since this is what “brands” the local station in theminds of its listeners. Therefore, the music selected to be played inthe background behind a vocal announcement must be both current andrepresentative of the music played by the station. The songs that aremost current are always changing and it is therefore desirable to keepre-formulating the station identifiers such that the most up-to-datemusic can be played together with the various voiceovers.

As a result, preparing these station identifiers involves a lot of workand audio engineering. Typically, an audio engineer at each local radiostation must combine the desired audio files (e.g.: the music or musicclips played together with the voice-over) into a single audio file thatcan be played by the local radio station. Unfortunately, the softwarethat is currently in use for this sort of radio production servicesrequires local assembly and expertise by a person with a high level ofaudio skills. There is simply currently no automated solution forcreating and downloading pre-mixed audio content that is uniquelybranded for each particular radio station. Thus, for audio material thatis meant to go out to hundreds of radio stations, existing tools do notallow the audio content to be individually customized for each of thesestations. Therefore, mass scale customization for local radio stationshas currently been impossible. It would instead be desirable to providea system for large scale internet distribution of audio content withindividual radio station customization.

Secondly, existing internet based audio mixing software does not allowthe combination of two or more WAV audio files using cuing time markerscodes to be output as a single audio file—with the possibility for thesetwo files to be playing simultaneously. It would instead be desirable toprovide a system in which audio files could easily be combined, but withtheir individual play times being staggered such that they may overlapwhile starting at different cueing times.

Lastly, existing audio software that is based on MP3 files does notadhere to consistent time code cueing markers. In other words, eachoutput file will have differences, even if made up of the samecomponents. It would instead be desirable to provide a system thatoperates with MP3 files, but does not have these limitations.

SUMMARY OF THE INVENTION

The present invention provides a system comprising a network hosted onremote servers for combining separate audio files into single combinedaudio files for preview and downloading to local users over theInternet. Preferably, this system is accessed and operatedsimultaneously by a plurality of local users, each viewing a web-basedinterface that may use FLASH and/or HTML.

In accordance with the present invention, the audio files are combinedon remote servers and are then sent to the various operators at theirlocal systems. During operation, two or more audio files are preferablycombined and are then heard simultaneously as a single output audiofile, based on a user-selected sequence. Each local operator istherefore provided with combined audio files that are complete andfinished with all the components that make up that piece integratedseamlessly.

The present invention is ideally suited for providing audio content to anumber of different local radio stations, such that the audio contentcan be individually customized for each of the local radio stations. Inaddition, the present invention provides an automated audio mixingsystem for a local radio station to mix their own local content intocontent supplied by a central provider. This pre-mixed content can thenbe downloaded and played on the local radio station (such that the localstation is “imaged” with name branded audio).

In accordance with the present invention, a radio station can subscribeto a service operating the present invention such that they can selectaudio components that are generic in nature and combine with localcontent customized to their station's name, theme or identity. Inpreferred aspects, these local radio stations can mix together two ormore audio files within a web platform to create a single audio filewhich then can optionally be output (i.e.: previewed and downloaded) aseither a WAV or MP3 file.

The final resultant combined file is delivered fully mixed by the systemto the operator. Thus, mass market customization can be provided forradio stations (wherein all the expensive and time consuming audiomixing is handled by the remote servers' software, rather than by audioengineers working at each of the local radio stations).

In one preferred aspect, the local “user side” of the present inventionprovides a web-based method of combining time coded audio files,comprising the following steps:

(a) a local operator using a web-based interface displayed on a localcomputer system to access a library of audio files stored on a remotesystem;

(b) the local operator using the web-based interface to select aplurality of the audio files from the library;

(c) the local operator using the web-based interface to request theremote system to combine the selected audio files into a single combinedaudio file comprising the selected audio files commencing play at audiocue markers;

(d) the remote system generating the single combined audio segment bycombining the plurality of selected audio files; and

(e) the local operator using the web-based interface to download orstream the single combined audio segment.

Opposite to the “user side” is the “administration side” of the presentinvention. The “administration side” of the present invention isperformed by an administrator at the remote system adding files to thelibrary or/or altering details or properties of the audio files in thelibrary. In one preferred aspect, the “administration side” of thepresent invention comprises the method of:

(a) the remote operator using a web-based interface to assign a sequenceorder to each of the library of audio files; and

(b) the remote operator using the web-based interface to assign theaudio cue markers to each of the library of audio files.

The present invention also preferably comprises a computer system forcombining time coded audio files, comprising:

a remote system hosted on a remote server, the remote system comprising:

-   -   (a) a library computer system accessing a library of audio        files;    -   (b) a processing computer system operating a program for        combining the audio files stored in the library of audio files;        and    -   (c) a communication computer system for receiving instructions        from a plurality of local operators at a plurality of different        local systems, wherein each of the local operators operates the        communication system to select audio files stored in the library        of audio files for combination by the processing system into a        single combined downloadable or streamable audio segment.

Preferably, the single combined audio segment is a downloadable file. Inalternate embodiments, however, the single combined audio segment isinstead streamed to the local user(s).

A main advantage of the present invention is that it provides a remotelyhosted web-based system for delivering audio content that is customizedto each of the specific local end users. These end users can choose userspecific audio content modules and then combine them with “global”content audio modules (i.e.: content available to multiple users). As aresult, the present system can generate single pieces of audio contentmade up of different audio modules. The present invention provides avery simple interface to create very complex mixed pieces of audio.

A further advantage of the present invention is that database managementperformed by the administrator at the remote system substantiallyreduces the amount of “audio engineering” that needs to be performed bythe local operators. For example, the administrator loads the audiofiles onto the system, sets up the audio cuing markers for the files,categorizes the files, etc. The present system is then pre-set to knowexactly how to combine the audio files when the user selects them. Thepresent audio mixing software combined with database management at theadministration (i.e.: remote) side permits the audio engineer managingthe present system to define all cuing markers and relationships betweenthe audio on the server side, so that automatic mixing is possible.Thus, the local operators do not need to manipulate parameters likevolume, equalization, compression, panning etc to create a mixed audiosegment.

DETAILED DESCRIPTION OF THE DRAWINGS (a) Overview

The present invention provides a web-based interface that permits aplurality of local users (working separately on their own localcomputers) to combine and arrange audio content on a network hosted onremote servers. The audio content comprises modularized short audioclips that can be combined in overlapping linear sequences. Thiscombined audio content can then be downloaded as a single audio segment(i.e. file or audio stream).

As will be explained, by providing audio content through a centralizedremote network, different local users can be provided with differentcontent and features. Some audio components and features may be providedto all users whereas some audio components and features may be providedto only some users, as is desired. Thus, the present system providesindividual users with options for personalizing or customizing theiraudio file production.

In accordance with the present invention, the audio content ismanipulated at a centralized network hosted on remote servers. This isfundamentally different from current existing audio mixing systems inwhich audio content is simply combined and manipulated at the user's ownlocal computer terminal.

(b) Exemplary Operation in the Context of Local Radio Stations

The present invention is ideally suited for the distribution andcustomization of syndicated radio audio content. When used in thiscontext, a plurality of local radio stations use the present inventionto mix audio by combining audio clips they select for downloading assingle audio files. When played back, these resulting combined audiofiles simply sound like the separate audio files being played one on topof the other. For example, one such audio file may simply be a tune orjingle (used by multiple radio stations) combined with a unique voiceover announcing the name of the particular local radio station.Moreover, the present invention provides a system to combine clips fromseveral popular songs all played together, but with a voice overannouncing the name of the particular local radio station.

As can be appreciated, there are many different radio stations playingthe same types of music. For example, there are a large number of radiostations playing “Top 40” music. They may each desire a “voice over”station identifier with their own local call sign broadcast over acombination of current Top 40 song clips playing in the background. Withthe present invention, it is possible to prepare the same combined Top40 song clips for all of these stations, but then have each of the localradio stations individually customize their own audio clips by mixing intheir local station call signs. With the present invention, each ofthese local radio stations can create, store and access their own unique“voice over” audio file. Similar arrangements can be made with localradio stations having other music themes (e.g.: Classical, Gospel,Alternative, etc. radio stations). For example, an audio filecombination of classical tunes can be made available to all of theclassical radio stations. Then, each of these classical radio stationscan combine this audio file together with their own particular stationname announcement “voice over” audio file. Other variations arepossible, all keeping within the scope of the present invention. Forexample, different radio stations of the same genre may still wish touse the same songs, yet combine them in a different sequence order.

(c) The Physical System Components of the Present Invention

FIG. 1 is a schematic illustration of the physical components of thepresent invention, as follows. A remote computer network system 10 isprovided for combining and managing time coded audio files. System 10 ishosted on remote servers, and comprises: (a) a library computer system20; (b) a processing computer system 30; and a communication computersystem 40. Library computer system 20 stores references to a library ofaudio files in a database that also holds all of the information aboutthe users, the audio files, the history of the audio files, the types ofaudio files, and session information. In one preferred embodiment, theaudio files themselves are stored in processing computer 30 and areference or link to the files is stored in library computer system 10.Alternatively, however, the present invention also comprises a system inwhich the audio files themselves are stored in library computer system10. Preferably, each of computer systems 20, 30 and 40 are separatelyhosted on different remote servers, as part of a remote network. As willbe explained further below, system capacity can be expanded by addingadditional (library, communication or processing) servers.

Processing computer system 30 operates a program for combining the audiofiles stored in the library of audio files. Processing computer system30 thus handles the merging and managing of the audio files.Communication computer system 40 is configured for communicating with aplurality of different local users through the Internet. The localoperators communicate with communication computer system 40 andcommunication computer system 40 communicates with each of librarycomputer system 20 and processing computing system 30. Processingcomputer system 30 and library computer system 20 also communicate withone another. The communication among computer systems 40, 30 and 20 allpasses through a private network router 15.

During standard operation, communication computer system 40 receivesinstructions from the local operators, such that each of the localoperators selects audio files stored in the audio file library forcombination by processing computer system 30 into a single combineddownloadable audio segment. This audio segment may be either adownloadable file or a segment streamable over the Internet.Communication computer system 40 communicates with the plurality oflocal operators through a web-based interface which may optionally beoperated in FLASH and/or HTML. (A screen shot of an exemplary web-basedinterface is shown in FIG. 2.)

Processing computer system 30 embodies and operates a computer programfor combining the plurality of audio files into a single combined audiofile. In optional preferred aspects, this computer program may be “SoX”(“Sound eXchange”™). It is to be understood, however, that the presentinvention is not limited to any particular audio software program; andthat “SoX” is merely one example keeping within the scope of the presentinvention.

The library of audio files preferably include both global audio files(available to many local users) and user-specific audio files (availableonly to one local user).

Each local operator communicates with the remote system throughcommunication computer system 40 to assign a sequence order to each ofthe plurality of selected audio files such that the plurality ofselected audio files can then be combined by processing computer system30 into a single combined audio segment comprising the selected audiofiles played in the sequence order, with each of the selected audiofiles commencing play at the desired cue markers. (Further explanationis presented in FIGS. 3A to 3C below).

Note: the present invention encompasses systems in which the localoperators only select the audio clips (and the audio clips are played ina pre-determined order), and also systems in which the local operatorsselect both the audio clips and their sequence of play.

FIG. 2 is a screen shot of an exemplary web-based interface as viewed bya local system operator. In accordance with the present invention, eachlocal operator communicates with communication system 40 through thisuser interface to select and combine audio files (by processing system30) into a single downloadable audio segment with the sequential audiofiles commencing play at pre-assigned cue markers. (Note: in thisembodiment, the cue markers for the various audio files are preferablypre-assigned by the system administrator when these files are initiallyloaded into the audio library).

This screenshot shows an example of three audio categories that thelocal user sees. The local users then have the power to choose differentcombinations of individual audio clips from these three categories tomake a final audio piece. Specifically, the user chooses a clip fromcolumn 1 called “voiceover V/O” (which plays first), followed by a clipfrom column 2 called “Artists” (which plays second) followed by a clipfrom column 3 called “Jingle” which plays third.

Examples illustrating the combination of various audio files indifferent playing sequences are shown in FIGS. 3A to 3C, as follows.

FIG. 3A shows three separate audio clips 100, 120 and 130. The localoperator accessing the system decides to select these three particularaudio clips (100, 120 and 130) from a large library of audio clips(stored on library system 20). As can be seen, audio clip 100 is shorterin playing time than audio clip 120. Audio clip 130 is shorter in lengththan either of audio clips 100 or 120. Specifically, audio clip 100 isselected to play first at time C1. Next, audio clip 120 is selected tostart playing at a time defined by second cue marker C2. Lastly, audioclip 130 is selected to begin playing at a time defined by cue markerC3.

Note: in optional aspects of the present invention, the cue markers C1,C2 and C3 can be assigned either as part of the properties of their ownaudio clips or as part of the properties of the other audio clips. Forexample, cue marker C1 may be assigned as a property of audio file 100.Thus, whenever file 110 is selected, it begins playing at the timedefined by cue marker C1. Similarly, audio file 120 always beginsplaying at the time defined by cueing marker C2. This embodiment isparticularly useful as follows. Returning to FIG. 2, each of theselections in column 1 (i.e.: voiceover “V/O”) may have a cueing markersat to play at time t=0. Thus, no matter which voiceover “V/O” selectionthe local operator chooses, it starts to play immediately. All of theselections in column 2 (i.e.: “artists”) may have a cueing markerpre-set to play at time t=4 seconds. Thus, no matter which artist isselected by the local user, their audio clip starts to play after 4seconds. Finally, each of the selections in column 3 (i.e.: “jingle) mayhave a cueing marker pre-set to play at time t=10 second. Thus, nomatter which jingle selection the local operator chooses, it starts toplay at time t=10 seconds.

It is to be understood, however, that the present invention is not solimited. For example, the cue marker C2 may instead be assigned as aproperty of audio file 100. Thus, when audio file 100 has played to thepoint in time defined by C2, then audio file 120 will start to play. Insuch an example, each of these audio clips has a pre-defined audio cuingmarker (information stored on the remote server side) that will governthe cue point for the next clip in the sequence to trigger.Specifically, returning to FIG. 2, the present system can be configuredwith a cuing marker in audio file 100 such that audio file 120 begins toplay at a queuing time defined in audio file 100.

In such preferred embodiments, audio files 100, 120 and 130 have cuemarkers assigned when they're loaded into the audio library. Theseindividual cue markers apply in all that particular file's interactionswith any other file. Therefore, when audio file 100 is selected it willhave a cue marker at, for example, 4 seconds, no matter what filefollows 100, the next file will always trigger at 4 seconds after audiofile 100 began playing.

In accordance with the present invention, the various audio files 100,120 and 130 are combined into a single audio segment 150. Audio segment150 is then provided for download by remote computer network system 10.Alternatively, audio segment 150 can be streamed to the user, asdesired. During a first portion of audio segment 150, a listener willfirst hear a portion of audio file 100. Then, the listener willsimultaneously hear both audio files 100 and 120. Later in time, thelistener will briefly simultaneously hear audio files 100, 120 and 130playing together. Still later, the listener will briefly simultaneouslyhear audio files 120 and 130. Finally, the listener will only hear audiofile 120 until the end of the combined audio segment 150.

It is to be understood that the present invention is not limited to thespecific embodiments and method of operation shown in the screen shot ofFIG. 2. For example, FIG. 3B shows an alternate way of combining theplaying sequence of audio clips 100, 120 and 130. In this user definedsequence, audio clip 120 plays first. After a few seconds, clip 120plays together with clip 100. Next, audio clip 120 then ends and audioclip 100 continues to play. Next, audio clip 130 plays together withclip 100. Next, audio clip 100 ends and the listener hears only audiofile clip 130 playing until the end. As can be seen in FIG. 3B, thetotal playing time of combined audio file 150 has a shorter play timethan combined audio file 150 in FIG. 3A.

(d) An Exemplary Method of System Operation

In one preferred method, the local operator interacts with remote system10 to perform the following steps:

Step 1: the operator uses a web-based interface (see FIG. 2) displayedon a local computer system to access a library of audio files stored inlibrary system 20.

Step 2: the operator uses the web-based interface to select a pluralityof the audio files (e.g.: 100, 120 and 130) from library system 20.These audio files are pre-organized (by the administrator of the remotesystem) into categories that define their content and also where theymay appear in a sequence, and what their cue markers are. In thisembodiment of the invention, the local operator is limited to selectinga sequence based on certain rules held on the server side.

Step 3: the local operator uses the web-based interface to request theremote system 10 to combine the selected audio files 100, 120 and 130into a single combined audio segment 150 comprising the selected audiofiles being played in the selected sequence order with the sequentialaudio files commencing play at cue markers “C” (see examples of FIGS. 3Aand 3B).

Step 4: remote system 10 generates the single combined audio segment 150by combining the plurality of selected audio files 100, 120 and 130.

Step 5: the operator uses the web-based interface to download or streamthe single combined audio segment 150.

In preferred aspects, the steps may be performed with the web-basedinterface operating in FLASH and/or HTML.

In preferred aspects, the steps may be performed by the local operatorcommunicating directly with communication system 40. Communicationsystem 40 then separately communicates with both library system 20 andprocessing system 40. For example, communication system 40 will informprocessing system 30 of the audio file sequence and cue markers Cselected by the operator. Library system 20 may also store sessioninformation, and communication system 40 may request this sessioninformation. After receiving the operator's instructions throughcommunication system 40, processing system 30 may then requestingsession verification from library system 20. Library system 20 will theninform processing system 30 that the session has been verified. Afterthis verification, processing system 30 will access the library of audiofiles (which may be stored in processing system 30 with references tothe files stored in library system 20). Then the audio mixing softwareprogram embodied in and operated by processing system 30 will combinethe operator selected audio files (100, 120 and 130) into the singlecombined audio segment 150. Finally, processing system 30 will then sendthe single combined audio segment 150 to communication system 40.Communication system 40 will then serve up audio segment 150 for previewand download by the local operator(s).

In optional aspects, processing system 30 may also send a download queueto library system 20. This download queue can be stored in librarysystem 20 and a copy of the download queue can be archived in processingsystem 30. Once the finished audio files are saved in the database, theuser's history can be reviewed and the finished pieces can bere-downloaded. The finished audio files can then be looked up and ifstill archived will not need to be recreated, but served as alreadycreated audio files saving valuable processing time on processing system30.

As such, in optional aspects, the following actions may be taken betweenand among the physical components of the present invention to achievethe preferred method of operation:

1. The user logs in through communication system 40.

2. Communication system 40 requests info from library system 20.(Library system 20 stores individual session information).

3. Library system 20 returns session information to communication system40.

4. Communication system 40 informs processing system 30 of theselections made by the local operator. (For example, communicationsystem 40 sends the file number for each audio file in the sequence andthe local user's ID (which it received from library system 20) toprocessing system 30).

5. Processing system 30 asks library system 20 for verification (toverify that the specific user is able to access the requested audiofiles.

6. Library system 20 tells processing system 30 that the session isverified. (After verification, processing system 30 requests the WAVfile name, length, and cue marker C for each selected audio file.)

7. The combined audio file generated by processing system 30 is sentfrom processing system 30 to communication system 40. (i.e.: processingsystem 30 then mixes the WAV files according to their sequence order,lengths and assigned cue markers C). Thus, sequential audio files aremixed into combined audio segment 150 starting at their successive cuemarkers (C1, C2, C3).

8. Processing system 30 gives the download queue to library system 20(and library system 20 saves it).

9. Processing system 30 can optionally pass segment 150 to communicationsystem 40 for direct downloading by a user.

10. Processing system 30 makes an archived copy of the download queue.

It is to be understood that the present system can be used in marketsand industries including (but not limited to) broadcast and mediamaterial, pod-cast and internet broadcasts, computer games, or any otheraudio application where audio clips have a length and a style defined sothat they interact in a similar way within a sequence.

For example, the present invention could also be used in a video gamethat wanted to incorporated someone's name in it. In such an embodimentof the present invention, the person's name could be added on the fly inthe middle of two pre-recorded effects. This is advantageous in that inthat it would save space on the CD/DVD of the game (and offload theaddition of the name sound file onto a server system). There would be noneed for a user interface. Rather, the game code would interact directlywith the web server.

An important advantage of the present physical system configuration isthat multiple communication, library and processing systems can each behosted on dedicated servers. As a result, it is possible to expandnetwork 10 as load requires (due to separation of communication, libraryand processing servers). At the end of every interaction (page load) thesession data is stored back into the library system 20. This allowsremote network 10 to expand and use round-robin style load balancing onthe communication server 40 without affecting the user experience.

This system allows for multiple library, processing, and communicationservers to be expanded as load requires. They can be addedasynchronously. The separation of services allows for unlimitedexpansion of this system. The processing system server 30 worksindependently of communication server 40 but requires a data store toorganize the files (such as library server 20). A processing systemserver 30 could easily have another interface built and accomplishdifferent mixes of audio, as long as it had records containing theproper information about the file. A plurality of processing servers 30could be added and put into the rotation of the communication server 20to handle a larger load. Library servers 20 can also be put intorotation with the use of data replication to handle a larger load.

(e) A Radio Station Example

In accordance with the present invention, audio content can bedistributed to multiple radio stations, with the audio content beingindividually customized. This is accomplished by delivering audio filesas “building blocks”. The present invention provides a platform forassembling these building blocks in a variety of different combinations,controlled by the local end user, without the need for specialisttechnical knowledge or equipment.

The present system is deal for delivering customized on-air “imaging”and branding material (e.g.: audio content that defines the image of aradio station, commonly known as “jingles” and “sweepers”). Individualradio stations can then use the present system to take these modularaudio files and combine them with “global” audio files (available tomany local operators), producing combined audio files for on-airdelivery. These “global” audio imaging modules can be updated in theremote server system on an on-going basis.

For example, FIG. 2 illustrates a screen shot where the user simplyhighlights a filename (in 3 columns) and then selects “preview”. At thattime, a completed audio sweeper or jingle is generated (as combinedaudio file 150). Alternatively, the user could instead select a“suggested” pre-programmed sequence (being a sequence of three audiofiles that are pre-arranged to reflect common radio industry audiorequirements).

FIG. 4 illustrates a screenshot where the local user creates a combinedaudio segment by selecting a “jingle”, followed by a “listener” followedby a “jingle”. The first column shows ‘jingles’ that may be used as thestart of the audio sequence and the third column shows ‘jingles’ thatmay be used at the end of the audio sequence. The user selects a firstjingle from the options in the first column. Next, the user selects apreferred “listener” from the second column. Note: the term “listeners”could instead be one of a number of other commonly used radio contentstyles, ‘artists,’ ‘beds,’ ‘music promo’, etc. Finally, the user selectsthe end jingle from the choices in the third column. Once an item hasbeen selected in all three columns, the user is able to preview theentire audio sequence, and choose to download, or they can amend any orall sections of the sequence.

For Example:

Audio file 100 is a ‘VO Front 102.5 KSFM’ that runs 14 seconds in total.It has a trigger point (cue marker C1) after 4 seconds. (If listened toalone, this audio file would be a voice saying the words ‘102.5 KSFM’and then some sort of ambience that runs for the rest of the piece).

Audio file 120 is a ‘Artist Sweep—Madonna, Timbaland, Black Eyed Peas’that runs 9 seconds in total, but has a trigger point (cue marker C2)after 7 seconds (If listened to alone, this audio file would be theartists saying introducing themselves and then maybe a drum hit with areverb tail at the end of the piece).

Audio file 130 is a ‘Jingle End KSFM’ that runs 5 seconds in total. (Iflistened to alone, this would be a sung vocal of ‘KSFM’ with appropriatesound effects).

The present system assembles this audio content such that the resultantaudio from audio file 100 plays for 14 seconds, after it has played for4 seconds, it overlays audio file 120 which runs for 9 seconds. Onceaudio file 120 has run for 7 seconds (audio file 100 has run 11 secondsat this point), the present system then overlays audio file 130. So, forseconds 12 and 13, all three audio files play simultaneously and thenfor second 14 audio file 100 continues to play in tandem with audio file130. Then, for seconds 15 and 16, audio file 130 plays alone.

The bottom section of the screenshot shows ‘pre-loaded’ sequences thatcan be retrieved with a single click (these are commonly used radiosequences that most radio stations require). When a pre-loaded sequenceis selected, the relevant components appear in the main sequencersection, the pre-loaded sequence can be downloaded as is, or it can befurther edited in the main sequencer section.

FIG. 5 illustrates a screenshot where the category ‘hooks’ is selectedfor the middle section of the main sequencer. When ‘hooks’ is selected,the middle column now allows selection of a sequence of three items tomake up the middle section. As such, the local user chooses three songs(items) specific to their playlist to include in the middle of a mixedaudio file, the local user may alter the order of these ‘hooks’ as theywish. Note: the present invention also covers the selection of more thanthree “hooks” to create longer middle sequences, as desired.

As can be seen, the users each log in and sees unique content related totheir particular radio station. The illustrated webpage is for “KissFM—102.5”. As can be seen, the audio content is laid out in “starts”,“middles” and “ends”. “Starts” and “ends” may be voiceovers (includingbut not limited to statements of the station's call letters), frequencyor other positioning statement. “Middles” are preferably global audiofile content (i.e.: audio files having a mass market appeal). The middlesection is preferably expandable to include more than one audio file(such that more complex sequences are an option).

As stated above, FIGS. 4 and 5 both show examples of a web-basedinterface through which a local operator chooses audio content tocombine. The local user chooses the appropriate “start”, “middle” and“end” (from the drop down menu) that best meets their desires. They havethe opportunity to preview the sequence (after it has been created asaudio file 150) and then download or change it. The system thus providesa “mix and match” interface in which audio files can be connected invarious combinations to create unlimited permutations of audio filecombinations. In addition, multiple audio pieces can be downloaded in asingle session, and preferably the display will show which sequences theuser has previously downloaded. Thus, FIGS. 4 and 5 illustrate detailedexamples of combining an audio “front” (audio file 100), “middle” (audiofile 120), and “end” (audio file 130) at local radio station 102.5 KSFM.

In various optional embodiments, “fronts” and “ends” may be userspecific and the “middle” section may be global. Also, the end user maynot wish to use a global middle section, but rather eliminate it toproduce shorter station pieces.

As stated above, content available audio files may be “global” or“user-specific”.

An example of a piece of global audio file content could be:

(a) Name—‘Music Promo Miley, Taylor, Britney’.

(b) Description—A 12 to 15 second piece that contains portions of songsfrom the various popular artists featuring Miley Cyrus' ‘Party in theUSA,’ Taylor Swift's ‘Lovestory’ and Britney Spears' ‘3’.

(c) Category—‘Music Promo’

An example of an end user specific piece of audio file content could be:

(a) Name—‘Jingle Frequency front 102.5 A’.

(b) Description—A sung vocal ‘102.5’. (Note: local user content may onlybe a front or end piece, column 1 or column 3 so that global content istagged at the start and end with user specific content).

(c) Category—‘102.5 KSFM/Fronts/Jingles’.

Thus, the local end user at station 102.5 KSFM can then assemble a musicpromo with pre-defined music, as follows: (a) the user chooses anappropriate “front” (in this case being ‘Jingle Front 102.5 A.’); (b)the user chooses an appropriate “middle” section (in this case being‘Music Promo Miley, Taylor, Britney’), and (c) the user chooses anappropriate “end” (in this case being a “voice over” for station KSFM”).

The software of the present invention then generates a preview of thesethree audio components mixed (as combined audio file 150). The end userthen chooses to keep this sequence for download, to modify it, or scrapit. Note: In preferred aspects, the present invention is not limited tosystems that combine three or more audio files. Rather, the combinationof two or more audio files is also contemplated within the scope of thepresent invention.

In another example, the end user at station 102.5 KSFM assembles a musicpromo of user defined music using “hooks”, as follows: (a) the end userchooses appropriate “front” (in this case ‘Jingle Front 102.5 A.’); (b)the end user selects ‘Hooks’ in the middle section; (c) a drop down menuallows up to 3 ‘Hooks’ to be chosen; (d) the end user selects ‘Party inthe USA’ as Hook 1; (e) the end user selects ‘You belong to me’ as Hook2; (f) the end user selects ‘Circus’ as Hook 3; and (g) the end userchooses an appropriate ‘end’, in this case “voice over End KSFM”. Thepresent system then generates a preview of these five audio componentsmixed (as a combined audio file 150). The end user then chooses to keepthis sequence for download, to modify it, or scrap it.

The present system looks at the cue markers C (which are “triggerpoints” for starting the next piece of audio). However, it does not cutthe previous piece of audio. Instead, it plays two or more pieces ofaudio simultaneously. In this way the present system is fundamentallydifferent from existing audio “playlist” systems that simply ‘play’audio sequences since the present system allows for multiple pieces ofaudio to be overlaid at different points in time.

The audio files can initially be placed into library 20 by an audio file“supplier” (which may be the owner/operator of remote network system 10and/or one or more of the local system operators) as follows:

1. The supplier first creates an audio file. (This audio file ispreferably encoded as a “.WAV” file).

2. The supplier uploads the audio file to the remote system 10.

3. The supplier tags this audio file with markers, possibly including,but not limited to the following:

-   -   (a) “Content Type”: i.e.: is the audio file “global content”        (available to all), or is the audio file “specific content”        (available to one single end user).    -   (b) “Sequence Number”: (i.e.: the assigned play sequence—whether        the audio file selected will always be the first, second, or        third audio file to be played in the final sequence the end user        puts together).    -   (c) “Cue Markers”: (i.e.: a marker in the audio file indicating        when the next audio file is to be played in the sequence. (Note:        the cue marker is not the same as the audio end point for the        particular audio file).

A directory structure is categorized from the inputted audio files. Thisensures that audio files that are distinct to a single end user arestored so that they are only available to that end user. Conversely,audio files that are to be made available to all end users arecategorized appropriately so as to be easily identifiable. The databasepreferably includes information to catalogue the audio files by type sothat it is in a structure to allow the local end users to quicklyidentify the individual audio clips they want to combine.

Each audio file can be stored in the library 20 using different fields,including but not limited to: local user ID, file pathway, cuing marker,length, the time the audio file was created, the time the audio file waslast uploaded, etc. Information about each of the local users can alsobe stored in library system 20 in remote system 10. For example, thelocal user's ID, their login name and security access questions can allbe kept in a database in library 20.

Preferably, the combined audio file can be downloaded in either WAV orMP3 format. WAV files are uncompressed, and therefore any audio cuemarkers attached to them will correspond to their exact time position onany audio system they're encoded or read on. In contrast, MP3s arecompressed. This could result in minute shifts in the audio in relationto its cue markers. Advantageously, files that are mixed in WAY can be“clipped” such that two high volumes don't overlap. This makes WAY amuch more reliable format for assembling multiple audio files that relyon cueing marker time code triggers. Therefore, the present process ispreferably done in WAY. However, WAV files are significantly larger thanMP3 files. MP3s are compressed and have to be decoded first. The user istherefore preferably given the option of downloading either in WAV orMP3 formats.

Preferably, processing system 30 automatically creates a WAV version topreview the sequence and this is added to its database (in librarysystem 20) for that end user so that if the end user previews the samesequence again it will retrieve the audio faster (as it does not have toread the markers again to generate). If MP3 format is chosen by the enduser, the present system 10 creates an MP3 copy of the WAV file andmakes it available for download. This MP3 copy is tagged to the end userand stored on the server database so that it can quickly be retrieved ifthe user wants to download it again.
